Abstract

For the application of the mechanical stirring method currently used in KR process to the new refining processes, the effect of baffles on the mixing of bath liquid and solid particles was investigated using a water model. The baffle whose width is 1/10 of the vessel diameter was enough to enhance the liquid-particles mixing. The LDV measurement showed the formation of the unsteady vertical flow by the baffle. The same effect on the mixing was observed by injecting gas from the bottom into the mechanically stirred vessel.
